Altair HyperStudy 2021 Release Notes
New Features
- Sampling Fit
- New approach that combines Space-filling DOE and Fit. It samples the design space and builds a fit model at user-defined intervals until desired cross-validation R2 value is achieved.
- Side-by-Side Post-Processing
- In Post-Processing, a new capability has been added to simultaneously visualize results of different forms in multiple windows.
- Altair Inspire Studio Model
- Inspire Studio is a hybrid modeling and rendering environment for 3D conceptual designs. The new connection enables users to perform geometric changes directly within HyperStudy.
- Model Conditions
- Defining conditions for models is now supported. Users can control the sequence of executions and whether a model is to be executed or not.
Enhancements
- Periodic Report Generator
- Periodic data extraction during evaluation is now supported.
- Multi-Execution for Each Model
- Multi-Execution can now be applied to multiple independent models running in parallel.
- Registering Python Function Registration via GUI
- External python functions can now be registered in the user interface as an alternative to preference file (*.mvw) route.
- ANOVA Calculation
- Previously, ANOVA was a mandatory part of building Least Square Regression models. It is now disintegrated from the model building process and is optional in Post-Processing.
- Improved Computational Efficiency of HyperStudy Fit Model
- Pyfit file is used in memory for evaluation which provides computational efficiency.
- Linked Variables in Trade-Off Panel
- Linked variables can now be displayed in Trade-Off panel upon request.
- Enhancements in AREA Tool
- Two enhancements have been introduced: normalized area difference and logarithmic scaling option for highly dynamic curves.
- New Layout for Solver Input Argument Dialog
- Arguments are now classified in two categories: Standard and Solver Arguments. Arguments are appended and visualized in stacked form.
- Automatic Preview in Expression Builder
- Expression field is divided into two windows to accommodate the expression and its preview. Preview update is automatic by default. However, users can opt for manual updates.
- Maximize Levels for Discrete Variables in DOE
- One-click option has been added to maximize levels for discrete variables in applicable screening DOE methods. Maximum and minimum levels along with values are displayed in table form.
- Monitory HyperStudy in Batch Mode During Evaluation
- Monitoring HyperStudy in batch mode is now supported. There are three available options to manipulate the process: exit HyperStudy, stop evaluation, and change multi-execution count.
Resolved Issues
- Evaluation times were incorrectly reported.
- Removing multiple models at the same time resulted in error.
- In Verification Approach, Delta Plots were incorrectly scaled in some cases.
- Adding a goal in approaches other than optimization invalidated the definition.
- Discrete design variables were not supported in Workbench model.
Announcements
- Future versions of HyperStudy will remove support for upgrading studies constructed with version 14.0 and earlier.
- Verification approach can no longer be added as a standalone approach anymore. However, it remains available within Fit and Optimization approaches.
- Korean Language is no longer supported.
- Multi-execution for HyperStudy Fit model is no longer supported.
- In Solver Input Arguments, keyword filespec has been replaced with filepath. Keywords filebasename and fileroot are decommissioned.
